I would suggest doing a self diagnostic to check for trouble codes first. Is your vehicle equipped with navigation system?, the self diagnostic is inbuilt in the control panel and here are the procedures. Let me know what you find.
HOW TO RETRIEVE A DTC
1.Turn the ignition switch ON (II).
2.Press the AUTO button and then the OFF button. Continue to hold both buttons down for 1 minute.
If there is any abnormality in the system, the temperature indicator will light up the segment (A through N) corresponding to the error. The temperature indicator will then alternate every second between displaying "88" (all segments lit) and the error code segment (A through N).
The system will only display the DTC when the AUTO and OFF buttons are pressed. If you release the buttons, the display will go blank. To return the display, simply press the AUTO then the OFF buttons again.
If there is no abnormality, the segments will not light up.
Resetting the Self-diagnosis Function
Turn the ignition switch OFF to cancel the self-diagnosis function. After completing repair work, run the self-diagnosis function again to make sure that there are no other malfunctions.
